Red dot using nvidia iray

loueteliot

Hello, i use the default nvidia iray setting and the genesis 8 female model with the iray material but when i render i have a lot of red dot all over the model here is a zoomed in picture 

I use an emisive shader as only light source and the dome is disabled, do you have any idea ? Thanks

Lighting via emissive objects can take a long time to converge - I suspect your render iss topping as it has taken more than the maximum time (two hours by default), still with a lot of noise to be resolved. Try increasing the maximum time in Render Settings under progressive rendering, or add more light to your scene. If the emissive surface is complex it may also help to use a simpler, lower polygon, item.
